CA 2414862

A proximity sensing device comprising an antenna unit having a substantially longitudinal antenna extending therefrom, the antenna being encased along a substantial part of its length between an interior encasement portion and an exterior encasement portion, said encasement portions being configured so as to substantially immobilise the antenna, and the exterior encasement portion being adapted to permit the transmission of electro-magnetic radiation therethrough. The proximity sensing device is particularly suitable for use within the fuze of a projectile. The proximity sensing device advantageously has a dipole antenna.

L'invention concerne un capteur de proximité équipé d'une unité d'antenne. Une antenne sensiblement longitudinale s'étend depuis cette unité. L'antenne est encastrée sur une partie substantielle de sa longueur entre une partie d'encastrement interne et une partie d'encastrement externe. Ces parties permettent d'immobiliser sensiblement l'antenne, et la partie d'encastrement externe assure la transmission des rayonnements électromagnétiques. Le capteur considéré est particulièrement adapté à une utilisation dans une amorce de projectile. L'autre avantage du capteur est qu'il est équipé d'une antenne doublet.
